CHINO — Two Los Angeles County sheriff’s deputies staying at separate sites on a Southern California campground were arrested after authorities said they pulled guns on each other and fired them into the air during a dispute over loud music.

No one was hurt, but Chino police said Dejay Barber, 44, of Mira Loma, and Matthew Rincon, 24, of Ontario were arrested for suspicion of negligent discharge of firearms.

Police spokeswoman Michelle Van Der Linden said Tuesday the two were released to the custody of Los Angeles County sheriff’s officials.

The deputies could not immediately be reached for comment. Sheriff’s spokesman Steve Whitmore said they were placed on paid leave while the case is investigated.

Whitmore said the pair allegedly brandished their handguns in a threatening manner and fired multiple rounds into the air.

“Alcohol is suspected,” Whitmore said in published reports. “This is gross negligence.”

Chino police said they don’t believe the deputies knew each other before the gunplay began.

They were arrested early Sunday morning at Prado Regional Park.

Whitmore said one of the deputies works with Los Angeles County courts and the other is in the department’s transit services division.

Chino police are asking that anyone with information about the confrontation contact them.
